STAMFORD, CONNECTICUT, ASSIGNORS TO UNDERWOOD ELLIOTT FISHER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE COMBINED TYPEWRITING AND CARD-PERFORATING MACHINE Application filed January 2, 1926. Serial No. 78,810.

simultanenously with the typing of the rec- 0rd upon a work-sheet in the typewriter. As lswell known, these cards are used in making groupings, analyses, tabulations, etc., of the items indicated by perforations in the cards. A line of data'under form headings on the work-sheet may include portionswhich need not be transferred to the record-card. Therefore, while said portions are being typed, the perforator must be inactive.

A feature of this invention is the provision of improved coupling means whereby the joint operation of the typewriter and card- .perforator may automatically be suspended and resumed at positive predetermined intervals without requiring the attention of the operative. v

The card for use in a perforating machine is designed for forty-five denominational columns, each to have space for twelve holes. Ten of the hole spaces in each column are for the numerals. Above the numeral or digit spaces in each column, are two extra spaces,

which are useful in grouping operations, coding, etc. These extra spaces are also combined with numeral spaces to represent alphabetical characters and other symbols. It will be understood that a space becomes effective when a hole is punched therein.

The blank card is automatically fed into the perforator so that its five hundred and forty hole-spaces are in register with a nest of five hundred andforty punches in the perforator. Said punches co-act with a perforated die-plate beneath the card to' punch holes in the card. During the punching operation, the die-plate and card are raised. This raises all the punches except those over the spaces to be'perforated. These are held down by rods or setting pins which were previously depressed and latched by operation of the perforator-keys. There is one setting pin in line with and over each punch. As the card and die-plate are raised, these helddown punches penetrate the card and punch a hole therein: Aspring-propelled carriage having twelve key-actuated pin-setting plungers traverses the forty-five denominational columns of setting pins from left to right in e'scapement cont-rolled denominational-selecting steps so that one column is set up at a time. When the carriage co-acting with the perforator-keys has traversed and set the pins so that the record holes may be punched, a punching cycle is initiated, during which a blank card is fed in and punched according to the pin-setting. While the blank card is fed in, the card punched inthe preceding cycle is ejected. The pinsetting carriage is then returned manually and this return automatically restores to normal position the pins which had been set.

Previously to the present invention, the typewriter and perforator were coupledfor joint operation by means which included an electric cable joining typewriter-key-actu ated electric contact devices on the type- -writer with electromagnetically operated devices for actuating the perforator-keys.

Thus when a typewriter-key is depressed an electric circuit to and including one or more of the electromagnetic devices is established by closin said contact devices and one or -mofe perforator-keys are actuated, it being understood that some characters are represented by two holes. With this arrangement, a foot pedal is provided whereby electric connection between the perforator and typewriter may be interrupted, with the result that during this interruption the perforatior is inactive while the typewriter-keys are operated in typing portions of a line of data not used on the card. This foot pedal is actuated by the operative and its use requires considerable deftness and co-ordination in depressing or releasing it at the right time. Through inopportune connection or disconnection of the two machines by the operative in using the foot pedal, the columns on the work-sheet will get out of register with the corresponding columns on the card, and holes will be punched in the wrong card columns. An error' of this kind is not apparent in most cases, except by a painstaking and tedious comparison of the perforated cards with the work-sheet.

What is provided therefore by this invention, inthe preferred form herein described and illustrated, are positive coupling means whereby the typewriter-carriage in its movements drives and automatically controls the movement of the card-perforator pin-setting carriage, said coupling means including devicesfor automatically suspending and resuming the joint operation of the typewriter and card-perforator, so that the latter may be inactive while data not required to be punched on the card is typewritten. The feature of positively coupling the typewriter and perforator carriages is disclosed in the co-pending application-of Alfred G. F. Kurowski, Serial No. 48,728, filed August 7, 1925, (now Patent No. 1,683,97 9, dated September 11, 1928) wherein are shown a rack on each carriage, meshing at all times with an intermediate pinion, and a modified type writer escapement-mechanism for moving the typewriter-carriage in steps of of an inch, which is the longitudinal spacing of the holes or columns on the card. The invention'disclosed insaid co-pending application was for the purpose of positively con necting the two carriages and typing a printed heading on cards, which were then inserted in the -,perforator and punched from the pin-setting made coincidentally with the y In the present invention, it is required and provision made that, while the typewritercarriagemoves in steps of letter-space extent, the card-perforator pin-setting and denomination-selecting carriage shall move in steps of denomination-spacing extent.

To this end, there is provided on the typewriter-carriage, a rack which meshes with a pinion rotatably mounted on a stationary spindle. Co-axial with said pinion and coupled therewith on the same spindle in a manner to be set forth is alarger pinion which meshes with a rack on the perforator pin-setting carriage. The spacing movements of said carriages are proportionate to their' respective pinion diametersl No change is required inthe typewriter escapement, but, as set forth in the aforesaid copending application, the propelling spring and escapement-mechanismfor the perforator-carriage are dispensed with and may be omitted from the perforator, because said I perforator-carriage is controlled by the typewriter carriage and its escapement-mecha- Insm. The two aforesaid pinions are devised so that one of them slides into and out of engagement with the other in the manner of a clutch. Both 'pinions have interlocking clutch-teethand the slidable pinion is actuon the typewriter-carriage. These camblocks, one at a time, and successively as the typewriter moves in a letter-feed direction, encounter an arm on the aforesaid disconnecting lever, and actuate said lever to disconnect the pinions an keep them discon nectedQwhile the typewriter-carriage travels the extent of the dwell on the particular camblock which is in engagement. The length and spacing of the cam-blocks are determined by the form on the work-sheet in relation to the form on the card.

A spring-,pressed-one-way pawl is mounted on said arm to engagethe cam-blocks and is diverted and tipped by the cam-blocks during the return movement of the "carriages. When the two pinions are disconnected, a spring-pressed extension on the disconnecting lever enters one of the circumferential notches provided in the pin-setting carriage pinion, and in this manner holds said carriage while thus disconnected from the typewritercarriage. It is necessary that this extensionof the lever be springressed because it encounters one of the teet 1 between the notches as soon as the disconnecting lever begins to move, and said extension must yield until the pinion has been. sufficiently rotated to allow the beveled-edge of said extension to slip into the notch.

The present invention retains and uses the key-actuated electric contact devices on the typewriter joined by a cable to electromagnetic devices for actuatingthe perforatorkeys. To completely suspend the joint operation of the two/machines it is necessary, besides disconnecting the carriages, that theelectric connection between the machines be interrupted, else whenever a typewriter-key is actuated, a pin or pins will be set up in the perforator at the column where the perforator-carriage stops when the two carriages disconnecting lever being diverted by and magnets to make and break the circuit for said magnets.

Provision is also made of means for manu-- ally disconnecting the two machines so that the typewriter may be used alone in regular typing work. This is done by providing the disconnecting lever with a handle and suitable means for holding the lever in disconnected position.

When the carriages are moved forward in letter-feed and pin-setting steps, intervals may occur, as already explained, during which the typewriter-carriage moves, but the perforator-carriage is stationary. During such intervals the coupling pinions are disconnected. Thus the typewriter-carriage moves through a greater number of steps than the perforator-carriage In returning the carriages, the perforator-carriage reaches its starting point and encounters a stop before the typewriter-carriage, because, during the return movement, the pinions are not disconnected at intervals, due to the pawl on the trailing over the cam-block. I

Itis necessary, therefore, that the length of the coupling rack on the perforator be of such extent in relation to its pinion that the teeth of said pinion may escape from the end of said coupling rack when the perforatorcarriage has returned to its starting position. The typewriter-carriage may then be further returned until its starting position is reached. A springsuitably app ied to the perforatorcarriage and its rack presses said rack to-. wardand against its pinion, so that the pinion will pick up the rack as soon as the carriages are to start forward again. At the end of the return movement of the perforatorcarriage, this spring will be slightly stressed, the rack moving a slight distancebeyond the normal stopping point before the teeth of the pinion escape while the typewriter-carriage disconnecting lever is divertedand tipped by,

is completing its return movement.

It has been explained how the pawl on the the cam-blocks during the return movement of the typewriter-carriage. Means areprovided, therefore, inthis invention for restoring the pawl to its normalposition relative to said disconnecting lever. This is necessary when a carriagefd isconnecting cam-block is in engagement at the beginning of the line. Such a cam-block is provided, therefore, with an elevated surface which engages a stud in the disconnecting lever. At the end of the return movement of the typewriter-carriage,

the pawl end of the disconnecting lever is thereby raised 'to enable the tip of the pawl to clear the cam-block, so that said pawl may swing back to its normal position.

Other features and advantages will hereinafter appear.

Numeral keys 15 andalphabet keys 16 when platen is revolubly mounted within a carriage 22 which moves upon carriage rails 23 and 24: on the main frame 25. A work sheet 21 is introduced at the rear'of said platen and fed around it by the usual means.

Said carriage is urged from right to left by a spring motor 26 on the typewriter-frame. A strap 27 connects the spring motor to the carriage. The type-bars engage a universal bar 28, movable rearwardly, to actuate an escapement-rocker 29 carrying escapementdogs 30, which co-operate with the teeth of an escapement-wheel 31 to effect step-bystep letter-space movements of thecarriage advantage with this invention, and is of the type which consists of a tabula'tor-key 35 pivoted on the rod 18 and providedwith a draw-link 36 that connects with a rocking bar 37 carrying a series of stops 38. By depressing the tabulator-key these stops move into the path of a carriage-stop 38 and simultaneously the carriage feed-rack 34 is raised from engagement with the pinion 33,

'- so that the spring motor 26 may effect column skipping or tabulating.

Power-driven means for returning the typewriter-carriage may be of the type disclosed inthe co-pending application of Alfred G. F. Kurowski, Serial No. 41,507, filed July 6, 1925 (now Patent N 0. 1,679,727, dated August 7, 1928). Said means ,(see Figure 12) include an electric motor 40 suitably geared to a clutch-member 41 which is keyed to a shaft 42 on which is slidably mounted a clutch-pinion 43 having teeth 44 to engage said clutch-member 41. The clutch-pinion 43 is operatively connected to a spring-pulled latch-link 45 which serves to keep the clutch disengaged. Said latch-link 45 may be tripped to engage the clutch by means of a lever and key 46 conveniently located near the typewriter keyboard. Said lever when operated raises the forward end of the latch link until a latching notch therein escapes from a holdingv edge. A spring 45 then" pulls the latch-link rearwardly to effect engagement of the clutch. When the latch-link is tripped to engage the clutch, a rearward extension 47, connected to said latch-link by means of a short shaft 47", serves to close a circuit to the motor by I means of suitable contacts within the switch-box 49, thereby starting the motor 40. The clutch-pinion 43 meshing with a rack 48 mounted on the typewriter-carriage then drives said carriage in its return movement. Said rack is mounted and arranged to actuate a line-spacing mechanism 48 before it picks up the carriage. When the carriage reaches the end of this return movement, a cam 50 on the carriage rocks the shaft 52 by means of a settabledog 51. This disengages the clutch-pinion 43 by means of the arm-and-link connection 53 to the slidable clutch-pinion 43, At the same time the latch-link 45 is restored, the circuit to the motor is broken.v and the motor stopped.

*A trip-key 54 is-pro'vided at the typewriter keyboard for starting an operating cycle of the card-perforator. Said card-perforator is the well-known Powers key-punch. This perforating cycle must precede the return of the carriage.

During this cycle a blank card 55 is picked from a stack 55 by means of a reciprocating picker 56 and pushed through a one-card aperture57, and thence to feed-rolls 58, 59 and 60. These rolls carry the card into punching position determined by stops 61.

In this position the card overlies a die-plate 62 which may co-act with punches 63, as will be shown. The feed-rolls 6O bear upon the card with limited pressure, so that they may "slip over the surface of the card when it reaches the stops 61.

The upper ends of the punches are guided by close fitting holes in a plate 64 supported by a, machine frame A. The punches are prevented from falling through by having enlarged heads 65. The punches 63 are guided by having a working fit in a bar 66, and the die-plate 62, forming a part of a frame 63*, after receiving a card, is moved upward and presents the card to the punches. This eifects perforation of the card when a punch or punches are held down. Punches ginning of such a cycle the stops 61 are withdrawn by cam devices, not shown, and the feed-rolls 60 are then free to pass the card to rolls 60 and thence into a receptacle 61 Each punch, of which there are five hundred and forty arranged in forty-live denominational columns of twelve digit punches, has above and in line with it a pin 67 which may be pushed down and latched, so that its lower end stops the punch as the card moves upward and is pierced thereby.

Each column of twelve pins has a latch-bar 68, provided with suitable edges to interlock with edges 69 on the pin 67 to hold said pin down when depressed. Each latch-bar and its associated twelve pins are devised to coact in a manner well known in the adding machine art, so that a depressed pin or pins are restored by depressing another pin or pins in the same column. l/Vhen a latch-bar is with drawn from a depressed pin, the pin is restored by a spring 7 O which presses the pin upwardly untila collar fastened to the pin strikes a plate 71. The lower end of the spring re-acts against a plate 72. 71 and 72 have holes which fitand guide the lower ends of pins, and said plates are fastened to bars 7 3 sn ported by the machine frame A. The upperiends of. the pins are guided by holes in plates 74 and 7 5supported by cross-bars '76 fastened to the machineframe A. The latch-bars 68 are slidably supported in the cross-bars 76 and are pressed against the pins by springs 77. Thus there is a bank of setting pins over the punches and wherever a hole is to be punched a pin is depressed and latched by its corresponding 1atch-bar 68.

Said plates w To efi'ect setting of the'pins, the perforator is ordinarily provided with a keyboard of These twelve keys correspond twelve keys. to the twelve hole spaces of each card column. (Jo-acting with said keys are twelve pin-setnting plungers 78 arranged to traverse the bank of setting pins 67 in a carriage7 9. Said carriage is retained andguided by rails 80 supported by themachine-frame A.

As shown in the aforesaid co-pending application, No. 48,723 relating to avcombined typewriter and card-perfbrator, the regular perforator-keys are replaced by solenoidactuated plungers- 81.'- The solenoids 143 (Figure 3) are mounted within a box 85 (Figure 1), and the plungers are operatively connected to the pin-setting plungers by means of flexible push Wires and bell-crank levers 82, to the horizontal arms of which the upper ends of the pin-setting plunge'rs 7 8 are attached. The flexible push wires are enclosed in flexible, sheaths 83. A universal bar 84 spring-pressed against the vertical arms of the bell crank levers 82 keeps the pin-setting plungers normally up. Each solenoid 143 is in a normally open electrical circuit which includesa source of current and a pair of separated contact devices 144 (Figure 3). Thesecontact devices underlie the typewriter-keys 15 and 16 and are arranged within a'case 141 through the top of which extend insulated plungers 86 by means of which the typewriter-keys when depressed close the contacts to energize the w solenoids. Whentyping a vcharacter represented by two holes in the card, the corresponding typewriter-key closes twosets of contacts 144 (Figure 3), so that two solenoids are energized and two pins set. The. wires between the contacts on the typewriter and the solenoids on the perforator are gath-= ered into a cable 87.

The trip-key 54, like the-typewriter-keys, is effective to actuate a solenoid 143 within the box 85. A plunger 88, by means of the flexible push wire within a sheath 89, is capable, when actuated by the solenoid, of operating a clutch mechanism, not shown, to start a cycle of the perforator; The details of this clutch-mechanism and its mode of operation are shown in the patent to Lasker,

No. 1,352,006, dated September 7, 1920. Theplunger 88'of the present invention replaces the controlling key shown in said patent to Lasken' 5 Operation of the clutch-mechanism connects the machine shaft 90 to a continuosly rotating motor-driven disk, not shown. .At the endof one revolution said machine shaft is automatically disconnected from the driving disk. During this revolution the feedrolls 58, 59, and 60 are rotated by means of the gear 91 on shaft 90. The frame 63 in suitableguidesis moved .up and down by means of arms 92 extending from the ends of a rocker-bar 93 pivoted at each end to the machine-frame A at 94. Said rocker-bar is rocked by means of an arm 95 projecting from the middle thereof, and which engages a grooved-face cam 96 by means of a follower roll 97. i 9

After the perforating cycle, return of the pin-setting carriage is effected, in a manner that will be shown, by depression of the carriage return-key 46 (Figure 12), and, during this return, pins 67 are restored by means described in the aforesaid co-pending application No.-48,7 23, relating to a combined typewriter and card-perforator. Said means include a roll .98 which is normally ineffective to operate the pin-restoring levers 99; Said roll 98 is mounted upon a lever 100 pivoted upon the pin-setting carriage and connected by a link 100 to another lever 101, also pivoted upon the pin setting carriage.

I During the final movement of the pin-setting carriage said lever 101 is rotated when a vertical arm 101 thereof meets an extension 102 from the machine-frame A. Said arm 101 lis then caught and held by a latch 103 pivoted upon the pin-setting carriage. The roll 98 is thus depressed and held in a position where it is effectiveto actuate the pinrestoring levers 99 during the return movement of the pin-setting carriage. Said pinrestoring levers in turn pushthe latch-bars 68 endwise to release pins that have been set.

At the end of the return movement of the pin-setting carriage, the latch 103 when it meets an adjustable stop 104 is rotated and withdrawn from the arm 101. -A suitable spring, not shown, then restores the lever 101, so that the roll 98 thereon is raised out of engagement with the pin-restoring levers.

The perforator pin-setting and denomina t-ion-determining carriage 79is driven and controlled by thetypewriter-carriage 22. To this end, a rack 106 is supported by means of brackets 1,07 upon the typewriter-carriage and meshes with a pinion 108. Said pinion 108 is coupled to a larger pinion 110, which it may drive by means of the clutch-teeth.

111 in both pinions. The pinion 110 meshes with a rack 112 mounted on brackets 113 projecting from the pin-setting carriage. Both pinions are revolubly mounted upon a stationary spindle 114, shown in detail in Figure 9. The spindle is reducedin diameter atits upper end to form a shoulder 115, which, in conjunction with a screw-head 116, retains the upper pinion 110. The lower pinion 108 may slide along the spindle, but is normally coupled to the upper pinion by means of a spring 109. A washer117isinterposed be tween the spring and lower pinion with which it 'may freely slide up andv down, but. said washer is prevented-from turning by engaging a slot"118. Said spindle 114 is suitably mounted upon a platform 119 ofvthe cardperforator (see Figure-2) pin-setting carriage is from left to right;

while a forward or letter-feed movement of the typewriter-carriage is from right to left. Thusthe carriages move in opposite directions. The stepping movement of both carriages is controlled by the spring motor and escapement-mechanism of the typewriter, the

escapement-mechanism and spring-motor of the perforator being dispensed with.

When. it is desired to use the typewriter alone in regular typing work, the lower pin- ,ion 108 may be separated from the upper pin- N ion 110 by means of a disconnecting lever 120 pivoted in a bracket 121 mounted upon Said" the platform 119.0f the perforator. disconnecting lever has an arm 120 bifurcated to embrace and engage the lower pinion by means of an annular groove 108 therein 2 and rolls 120 Said disconnecting lever may be manipulated by means of a handle 122 thereon, when it is desired to use the typewriter alone in regular typing work. From this handle extends a clip 122*, which may be caught by the edge of the screw-head 116 to hold the lever in a position for disconnected pinions. When said pinions are disconnected, the connection between the typewriter-keys and perforator-setting mecha- 5 nism also becomes inoperative, as will be shown. i

For the purpose of this invention, means are provided to automatically actuate the disconnecting lever before and after typing certain parts of a line on the work-sheet not required to be punched in the card. To this end, the disconnecting lever 120 is provided with an arm 123 carrying a spring-pressed one-way pawl or trip 124. Said pawl or trip has an inclined cam-face 1 24 by which it may ride over cam-blocks 6r tappets 125'and be lifted thereby during a letter-space movement of the typewriter-carriage to effect the separation of the pinions, prevent the setting of the punches and establish a non-punching setting zone, as shown in Figure 6.

It is necessary to use a pawl on the disconnecting lever, because said lever must be disengaged from the cam-block at the end of' the last step thereon. In this way the typewriter-carriage pinion does not rotate while being reconnected to the pin-setting carriage pinion. This necessitates an abrupt disen- CJ gagement'of the disconnectinglever from the cam-blocks and is accomplished by having' shear surfaces at the ends of the cam-blocks and at the escaping edge of the disconnecting lever. Said escaping edgemust therefore be in the form of a tripping pawl so as not to vibrate the lever 120 during a return-movement of the typewriter-carriage. I

The cam-blocks 125 vary in length predetermined by the number of letter-space distances the typewriter-carriage is to take while joint operation is, suspended; Said camblocks have square stems 125*, by means of which they are secured to the coupling rack 106 on the typewriter-carriage. These stems closely fit and extend through square holes 126, spaced in staggered arrangement in said coupling rack. A locking bar 127 rotatably mounted in brackets 128 and 129 (see Figure 4) and provided with a knob 130 and detent devices 131 secures the cam-blocks in a manner clearly shown'in Figure 11. A quarter turn of the locking bar frees the stems of the cam-blocks when it is desired to withdraw the cam-blocks or rearrange them upon the coupling block 106.

When the disconnecting lever is actuated."

to disconnect the pinions, a rod 132 pivoted to said disconnecting lever at 132 is thrust downward. This separates electrical contacts 133 contained in a box 134 having a suitable slot 134 to guide said rod. Said contacts are in the common lead to the electrotypewriter-keys are actuated. Thus complete automatic suspension of joint operation of the typewriter and card-perforator is accomplished, through disconnection of their respective carriages and breaking of the electrical connection between the two machines by means of the aforesaid disconnecting lever and cam-blocks. sumed when the escaping edge of the disconnecting lever pawl drops off the cam-blocks. r The work-sheet 2P in the typewriter, Figure 1, shows a form-heading beginning with a name. Lines entered under this heading begin with data not wanted on the card. In such cases when suspension of joint operation of the two machines occurs at the beginning of a line, a modified cam-block 136 is provided to effect disconnection of the two machines. This cam-block differs from the other cam-blocks in having an auxiliary camsurface 136 elevated above the regular surface 136". By means of a pin 137 in the arm 123 of the-disconnecting lever 120, this auxiliary cam-surface serves to disconnect the pinions, break the contacts 133, and raise the pawl end of the disconnecting lever, so that Joint operation is rethe tip of the pawl swings clear, and the pawl 1 136 moves the disconnecting lever 120 enough i to permit the clip 122 to be caught by the screw-head 116. When the carriages are disconnected, the pin-setting carriage must b e positively held.

tioned that the under surface or edge of the extension meets the upper surface of a tooth in order that the extension may easily override the tooth and slip into the succeeding notch.

During the forward movement of the type-u writer-carriage, the pin-setting carriage is disconnected and stationary at intervals, and

thus the typewriter-carriage moves through a greater number of steps than the pin-setting carriage. But during the greater part of the return movement of the carriage, the disconnecting lever is inoperative, due to the pawl thereon being tipped by, and trailing over, the cam-blocks. Therefore, whenever there are intervals of disconnected carriages during the forward movement, the pin-setting carriage, during the return movement, will reach its starting point and encounter a stop before the typewriter-carriage. The pinsetting carriage rack 112 is ofsuch length, therefore, that only the last tooth thereon is in engagement with its pinion when the pinset-ting carriage has reached its starting position. One or two steps before this, the pinsetting carriage has engaged and stressed a spring 140 fixed to the machine-frame A, and, as the typewriter-carriage completes its re turn movement, this spring is stressed a little more by a slight further movement of the pin-setting carriage which occurs as the teeth of its pinion push aside said last tooth of the rack and escape therefrom. This results in a ratchet-like action between the last tooth on the rack and the teeth of the pinion. As each pinion tooth escapes, said rack is pressed back toward and against the pinion, so that the pinion will readily pick up the rack as soon as both carriages are to start forward again. A stop 142 which backs up the spring at 1 12 prevents excess return movement of the pin-setting carriage. The linear pitch of the rack 106 and pinion 108 equals the letter feed pitch of the typewriter-carriage. In order that the pinions, racks and the'parts related thereto. may not get out of register with-each other it is necessary that the pin- P ions 108 and 110 have the same number of teeth, and that the number of notches-110 and the number of clutch-teeth 111 equal the number of teeth in each pinion. Thus one step ofeach carriage is equivalent to a notchto-notch or tooth-to-tooth movement. The

' typewriter is mounted upon a suitable frame 145 extending from and supported by the perforator-machine-frame. t Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described our invention, we claim:

1. In a combined typewriting and perforating machine, the combination with a movable typewriter-carriage having a rack, type- Writer-keys, perforator-setting mechanism including a movable carriage having a rack, and connections whereby said typewriterkeys may be effective to actuate said perforator-setting mechanism, of coupling and uncoupling means, whereby said carriages are-connected or disconnected, said coupling and uncoupling means consisting of two co} axially-mounted pinions, each one thereof engaging one of said racks, and each one thereof having clutch-elements, whereby said pinions are coupled'or uncoupled, one of said pinions being slidable into and out of engagement with the other pinion by means of a spring and a lever, said lever being actuated to uncouple said pinions against the reaction of.
